It's a line-reactor class component — the 7 % relative throttling factor means it presents about 7 % impedance at the line frequency, which limits harmonic current draw from the supply and smooths the voltage waveform seen by downstream drives or converters. The 0.0026 H inductance and 189 Hz resonant frequency tell you it's tuned to suppress harmonics around the 3rd and 5th orders, common in 6-pulse rectifier front-ends. The 15 kvar reactive power rating gives the bank sizing for power-factor correction applications. IP00 means no enclosure — this is a chassis-mount component for inside a panel or cabinet. Dimensions are 0.219 m wide by 0.179 m tall by 0.143 m deep, so plan for about 220 mm of rail or plate width and allow clearance around the screw terminals for a wrench. The screw-type main circuit connections accept standard lug or ring terminals; no special tooling needed. Thermal class B insulation (130 °C continuous) means it can run at 40 °C ambient without derating, but above that you'll need to follow the standard thermal curve for class B materials. The 24.1 A maximum is the short-term overload ceiling, likely for starting inrush or momentary overload conditions. The 87 W power loss at rated load is the heat you need to vent from the enclosure; at 21.7 A and 0.0026 H, that's about 0.19 % of the apparent power, which is typical for a 7 % impedance reactor. The 189 Hz resonant frequency means the reactor and its associated capacitor bank (if used) will resonate at that frequency — keep the drive's switching frequency and any harmonic sources away from that point to avoid amplification.","metaTitle":"SIDAC 4EP4001-5MS00 Filter Reactor, 21.7A, 400V, 3-Phase","metaDescription":"SIDAC 4EP4001-5MS00 3-phase filter reactor, 21.7A rated, 400V AC, 50Hz, 7% throttling, IP00.
